MOTGR-PLOW.

Application filed December 29, 1914.

To all whom it may concern:

Be it known that I, CARL GLEIGHE, a citizen of the German Empire, andresident of Berlin, Germany, have invented certain new and usefulImprovements in Motor-Flows,

of which the following is a specification.

My invention relates to improvements in motor plows, and moreparticularly in plows, in which the plow bodies or shares 10 are securedto a plow beam which is disposed obliquely of the longitudinal axis ofthe plow, which construction is advantageous for the reason that asingle plow beam is used for Supporting several shares and that the saidbeam can be secured and braced in a simple way relatively to the frameof the plow so that the plow is simple in construction and its weight iscomparatively low. However, the construction is objectionable in thisrespect, that there is little space between the shares andthe obliquebeam for permitting the passage of the soil which has been lifted by theshares and the moldboards. Thus the said space readily becomesobstructed by the soil, particularly where the soil is heavy and loamyor covered with vegetation.

The object of the improvements is to provide a plow of this class inwhich this ob- 80 jeotion is removed and in which the plow shares aresecured to the beam by means of an upright arm which is secured to thebeam through the intermediary of a block or filling piece which embracesthe beam at its inner or outer side with upper and lower flanges or lugsand is secured thereto by clamping members. Thereby I am enabled todispose the plow shares in any desired positions on the beam, and thebeam is not weakened by holes made therein for receiving screw bolts orthe like for holding the shares in positions, but the stress on the beamis reduced at the points where the shares are connected to it, which isimportant because in the operation of the apparatus these parts of thebeam are subject to high stress.

For the purpose of explaining the invention an example embodying thesame has been shown in the accompanying drawing, in which Figure 1 is aplan view of a part of the frame of a plow with a share secured theretoshown partly in section; and Fi Specification of Letters Patent.

2 is a partial vertical section substantially on the line 2-2 of Fig. 1;

As shown the frame of the plow is provided with an oblique beam 3 towhich plow share carriers 2 are connected one of which only is shown inthe drawing. The share is shown at 1. The plow share carrier 2 issecured to the outer face 7 of a block 4: by means of screws 5 and 6,and the block is formed with upper and lower flanges ll embracing thebeam 3 and with ears 12. Through the said ears and plates 13 clampingscrews 8 and 9 are passed which hold the block 4 in position. The screwbolt 6 is passed through a sleeve 10.

By securing the shares to the beam in the manner described, they can besecured there- 7 O to at any point of its length, since upon looseningthe screws 8, 9 the block 4: can be slid freely lengthwise upon the beam3. Any strain tending to twist or turn the blocks 4L relatively to thebeam 3, will be 5 borne by the flanges 11 and the parts of the beamengaged by them, and will not fall upon the clamping devices (screws 8,9) which secure said block in position on the beam. The clamping devicesare thus re lieved of any lateral or bending strain, and there is nodanger of the blocks turning on the beam when the heavy strain due tothe reaction of the plow share against the soil arises. This usefulresult is obtained with greater certainty when, as shown, the outervertical surface 7 of the block 4, against which the carrier 2 rests, islongitudinal, that is to say, parallel to the direction in which theplow is adapted to travel.

I claim herein as my invention:

1. In a plow, a plow-frame having an oblique beam, blocks shiftable onsaid beam lengthwise and each having its outer vertical face in a planeparallel to the direction in which the plow is adapted to travel, plowssecured to said blocks at the outer surfaces of the blocks, clampingdevices for securing said blocks to the beam at different points of itslength, and means on said blocks to relieve said clamping devices of thestress exerted by the plows.

2. In a plow, a plow-frame having an oblique beam, blocks shiftable onsaid beam lengthwise and each formed with upper and lower flangesembracing the beam, and each having its outer vertical face in a planeparallel to the direction in which the plow is adapted to travel,clamping devices for securing said blocks to the beam at differentpoints of its length, and plows secured to said outer vertical faces ofthe said blocks.

3. In a plow, a plow-frame having a beam, a block slidable lengthwise ofthe beam, but held against turning thereon, said block having a face ina plane parallel to the direction in which the plow is adapted totravel, and a plow-share connected With said block rigidly at said face.

In testimony whereof, I have signed this specification in the presenceof tWo subscrib- 15 Copies of this patent may be obtained for five centseach, by addressing the Commissioner of Patents, Washington, D. 0.
